Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Two intervention arms corresponding to 30 mins and 45 mins of external counterpulsation (ECP)treatment per session. Participants in both intervention arms will have 3 sessions/week for 7 weeks.
Treatment involves the participant lying on a bed with cuffs around the legs and hips. The ECP treatment involves the cuffs inflating and deflating every few seconds to change the blood flow returning to the heart.
The sessions will take place at The University of Queensland, St Lucia and will be provided by a trained technician.
Intervention adherence will be assessed as the number of visits attended from the 21 possible.
Intervention code [1] 298991 0
Treatment: Devices
Comparator / control treatment
Sham treatment involves the participant lying on a bed with cuffs around the legs and hips. It is sham because the cuffs do not inflate and deflate.
The sessions will take place at The University of Queensland, St Lucia and will be provided by a trained technician.
Control group
Placebo
